Struct CapabilitySetDiff 

pub struct CapabilitySetDiff {
    pub added_tags: HashSet<Tag>,
    pub removed_tags: HashSet<Tag>,
    pub changed_metadata: Vec<MetadataChange>,
}

Structural difference between two CapabilitySet values.

Returned by CapabilitySet::diff. Carries:

• added_tags: tags in self that aren’t in prev.
• removed_tags: tags in prev that aren’t in self.
• changed_metadata: per-key metadata changes (Added / Removed / Updated). Key renames surface as Removed + Added, not as Updated, since the key identity changed.

The diff is the input shape for event-driven placement updates, capability-change dashboards, and delta-based metadata propagation. For the structural ops shape consumed by the propagation path, use crate::adapter::net::behavior::diff::DiffEngine::diff.

Fields

added_tags: HashSet<Tag>

Tags newly present in self.

removed_tags: HashSet<Tag>

Tags that were in prev but are no longer in self.

changed_metadata: Vec<MetadataChange>

Per-key metadata changes, in key order.

Implementations

impl CapabilitySetDiff

pub fn is_empty(&self) -> bool

True if no tags or metadata entries differ.

Trait Implementations

impl Clone for CapabilitySetDiff

fn clone(&self) -> CapabilitySetDiff

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CapabilitySetDiff

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CapabilitySetDiff

fn eq(&self, other: &CapabilitySetDiff) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
